Come hang out in /r/ABraThatFits. Maybe that'll change your mind about how many women have been poorly fitted into your company's size range.

I am not saying that sub is an adequate sample to establish overall size distribution, but instead think that you can apply knowledge gained on that sub to the experiences you have had. I would be incredibly surprised if you hadn't poorly fitted someone accidentally.

Are you sure that is your size? You might try heading over to /r/ABraThatFits, as a 36D is not actually that common of a size (and not a large one by any measure). Moreover, even if that is your size, plenty of people can recommend the type of bra you are looking for from a brand that will work for you :)

Go get a coffee while she browses, man.
